Summary
General surgery residents need better education on deep vein thrombosis (DVT) risks and prophylaxis. Misunderstandings about risk factors and treatments like low-molecular-weight heparin (LMWH) can impact patient safety.
Area of Science:
- Medical Education
- Surgical Outcomes
- Thromboprophylaxis
Background:
- Postoperative deep vein thrombosis (DVT) contributes to significant patient morbidity and mortality.
- Effective patient risk stratification and prophylactic measures are essential for preventing DVT.
Purpose of the Study:
- To assess general surgery house staff's understanding of DVT risk factors.
- To evaluate knowledge of DVT prophylaxis strategies, including vena cava filters and low-molecular-weight heparin (LMWH).
Main Methods:
- A confidential survey was administered to general surgery residents.
- The survey covered DVT risk factor recognition, risk estimation, and prophylaxis practices.
Main Results:
- Key DVT risk factors like obesity, immobility, malignancy, and prior DVT were well-recognized.
- Risks such as age >40, myocardial infarction, lupus anticoagulant, varicose veins, and Factor V Leiden were poorly recognized.
- DVT risk in cancer patients was underestimated, and indications for vena cava filters and LMWH were frequently misunderstood.
Conclusions:
- Specific educational gaps regarding DVT risk and prophylaxis were identified among surgical residents.
- Targeted educational interventions can improve decision-making in thromboprophylaxis for young surgeons.
